The ShotLock Solo-Vault was designed as a universal shotgun mounting platform with the ability to integrate with the greater majority of pump, semi-auto, over and under, side-by-side, and pistol grip shotguns on the market today.

There are a few shotguns that the Shotgun Solo-Vault will not work with, and a handful of aftermarket accessories that will also prevent proper fitment inside of the ShotLock. We have done our best to identify as many of these shotguns and add-ons as we can, and have compiled a list below of known shotguns that either will not fit with standard equipment, come with accessories that will not fit, or have incompatible setups.

For an image gallery of compatible guns, please click HERE (link to gallery page in new window).

Known shotguns that are not compatible:

CZ 12-gauge side-by-side (gun barrels at the break are too wide)

.410 shotguns are not compatible with the ejection port hanger; however they will work using the trigger mounting blocks

Benelli M4 (ghost rings on tactical rail prevent securely putting this weapon in the ShotLock. The stock Benelli M2 will work however)

We have had some success with shotguns that have pistol grips and ghost rings or side saddles on the receiver fitting in the AR Solo-Vault.

Will my rifle fit in a ShotLock?

In most cases, no, but we will not rule it out entirely. The product was designed for shotguns but may work with some semi-auto rifle configurations.

Are there alternative ways to secure a shotgun in a Shotgun Solo-Vault?

There are many different ways to secure your shotgun in a Shotgun Solo-Vault. A shotgun can be mounted with the trigger outside of the vault, provided it is secured using the ejection port hanger (shotgun must be a side-ejecting pump shotgun). The hanger will be inserted into the ejection port preventing the gun from being discharged, even though the trigger is exposed. See an example below:

Can I mount the Shotgun Solo-Vault upside down, or reverse the way the door opens?

The Shotgun Solo-Vault can be mounted vertically or horizontally, with the door facing whichever way necessary to suit your purpose.

Handgun Solo-Vault

Is my handgun compatible with the Handgun Solo-Vault?

The Handgun Solo-Vault is designed to fit a greater majority of full-framed handguns (up to a 1911 size) on the market today. However, there are some aftermarket accessories that may prevent your handgun from being able to fit inside of the Handgun Solo-Vault.

Some aftermarket accessories that may not be compatible with the Handgun Solo-Vault:

Scopes

Flashlights

Extended magazines

Can I secure the Handgun Solo-Vault using a locking cable?

The Handgun Solo-Vault comes with two cable ports (holes) located in a corner opposite of the locking mechanism. Any 5/16” cable will fit in these ports. Alternatively you can use a padlock as shown in the picture below:

Is there enough room inside for an additional magazine alongside my handgun?

This will depend on the size of your handgun, but often times there is ample space to store an additional standard size magazine, or more, inside of the Handgun Solo-Vault. The Interior dimensions of the Handgun Solo-Vault are 9" x 7" x 2".

Troubleshooting M Series models (Mechanical)

Problem: The knob spins but doesn’t unlock the ShotLock.

Answer: The M-Series locks have a built in clutch protection. If you put too much pressure on the knob without entering the correct combination, it will spin all the way around back to the “LOCK” position. This simply means you did not enter the correct combination. If you have lost the combination, use the key override to access your vault and change the combination.

Problem: The default combination of 1-2-7-8 does not open the ShotLock.

Answer: If the default combination does not work, please access the ShotLock using the key override and follow the manual’s instructions on changing the combination.

Problem: While changing the combination with the pins removed, I can’t get one or more of the pins to seat properly back into place.

Answer: Make sure the marked side of the pins (either a letter or an “O”) are facing the TOP side of the locking module, and that you are holding the unlock buttons and the center slide button down as you place the pins back into place. They must go in straight down; if angled they will not seat properly. Once inserted correctly, they will be able to be pushed down (with a distinct “click”), and they will stay depressed until you press another button.

Problem: While changing the combination, I lost one or more of the combination pins.

Answer: If you have lost one of the pins marked “O”, which do not affect the combination, the lock will still function. There will be no friction when the button is depressed and may be obvious the button is not in use, but it will still work. However if you have lost one of the lettered pins (A through E), the lock will not function and you will need a replacement pin set. Those can be purchased from ShotLock by calling our Customer Service Line at 1-800-852-0400.

Problem: The metal cover won’t slide back into place after changing my combination.

Answer: Most likely the locking module is not seated correctly in place. It must have the “TOP” side facing up, and be properly seated in its cradle.

Problem: I have lost my key override.

Answer: Key overrides will vary from unit to unit and therefore cannot be replaced. If you are worried about losing your keys, a good locksmith may be able to make copies.

Problem: I have lost my combination, and my key override (door still open and unlocked).

Answer: If you have lost your combination for any reason, and your key override as well, the combination can still be reset using the provided instructions in the manual. You do not need to know the previous combination to set a new combination. However, key overrides will vary from unit to unit so a replacement key is not possible.

Problem: I have lost my combination, and my key override (door is shut and locked).

Answer: If you have lost your combination for any reason, and your key override as well, and the ShotLock is closed and locked, unfortunately there is no way for us to get you back into your ShotLock. Key overrides will vary from unit to unit so a replacement key is not possible. If you need to access the contents of your ShotLock, you will either need to call a locksmith or call our Customer Service Line at 1-800-852-0400 and we will provide you with instructions on how to drill the vault open, destroying the ShotLock in the process.

Troubleshooting E Series models (Electrical)

Problem: What size Allen key do I need to open the battery panel?

Answer: You will need a 2mm sized Allen key.

Problem: The knob spins but doesn’t unlock the ShotLock.

Answer: The E-Series locks have a built in clutch protection. If you put too much pressure on the knob without entering the correct combination, it will spin all the way around back to the “LOCK” position. This simply means you did not enter the correct combination. If you have lost the combination, use the key override to access your vault and change the combination.

Problem: The default combination of 1-2-3-4 does not open the ShotLock.

Answer: If the default combination does not work, please access the ShotLock using the key override and follow the manual’s instructions on changing the combination.

Problem: The correct combination is not unlocking the ShotLock.

Answer: Make sure you are hitting the “OK” button after entering the current combination. If that does not work, use the key override to access the vault and change the combination.

Problem: While changing the combination, the ShotLock emits a double beep, and the combination does not work.

Answer: A double beep means there was an error while changing the combination. Simply restart the changing combination procedure (accessing with the key override if necessary), and make sure you follow the instructions closely; you will hear a long beep once finished.

Problem: I have lost my combination, and my key override (door still open and unlocked).

Answer: If you have lost your combination for any reason, and your key override as well, the combination can still be reset using the provided instructions in the manual. You do not need to know the previous combination to set a new combination. However, key overrides will vary from unit to unit so a replacement key is not possible.

Problem: The batteries have died and I am unable to open the ShotLock.

Answer: Use the key override to access the ShotLock and replace the internal batteries.

Problem: The batteries have died and I have lost my key override.

Answer: As long as you know the current combination, you can use the battery backup provided to restore power temporarily to the ShotLock, allowing you to enter your combination and gain access. At this point you can replace the internal batteries.

Problem: The batteries have died, I have lost my key override, and I have lost the battery backup.

Answer: In this case, provided you still know the combination, you can use any power source that is compatible with a 12v jack that is found on the ShotLock to temporarily power the ShotLock, unlock it and replace the internal batteries.
